CORRUGATED lWALL PLATE.

i Appiieation filed septeniber`1a1e2a., serial No. 738,450.

lThe invention' resides in formingcorrugationsvorembossnients in a metallic plate so as to increase its strength toresist exterior loads 'appliedupon it. By forming said corruga .tions or embossments integral with the plate,

considerable` fabrication of other parts and riveting is eliminated, and furthermore, the

, to orm them as it isjnecessary not only toV ultimate weight of the structure is retained.

' frequently fracture; furthermore, the diii-Y at aininimum. n Y Y y l Y 4Suchintegrally reinforced plates arees* peciallyy adaptable Afor end walls o'railway freight cars where the sitting of the-lading` causesl severe impacts against-y the end wall.

These integral reinforcements also, resist the v tendency to buckle, due to the torsional and weavingl movements of ,the car inv service'.

Such plate may also Vbe used for the Hoor or roofof a. railway car. y

Such corrugations or embossment-s are mechanical beams andcan be consideredk and Calculated as such.V

Car *.wallk structures have been inanufao-V 'tured'and are .in extensive use wherein a.

series 'of straight parallel corrugations are. formed in the plate whichv terminate within the edges thereof to form flat margins. Each.

the corrugations terminate within thee'dges of the plate, considerable pressure 1s required bend the metal butalso 'to stretchand thin it; in fact, the plates are heatedto ai Cherry red to make such deformation vpossi-ble with-I out tearing the metal. This heating isexf Vpensive and also .handling cold plates. is n much faster than handling hot, plates, which considerably aects the output of the plant.' Higher grade steel plates must be used where stretching is required.

It has been proposed to extend the coi'ruga tionsto the opposite edges of the sheet (see Murphy PatentpNo. '1,313,106 ,2 August- 12, 1919), so thatfthe corrugations'may be bent or folded in the steelplate, without'streteh- 'ing' or heatingV it. Corrugated angles. and separate caps have been proposed to weatherv prooi that portionl of the. car adjacenty the theear, it would ruin certain' ladings.

YWhen a load is imposed rupon a corrugation which extends to the opposite edges of the plate, the corrugation has a tendency to Vopen up, i. e., forthe two Walls to separate.

This may beprevented by securing them together, for instance, as shown by rivets16 or such action may be resisted by securing the plate to the -adjacent frame member of the car (corner post if the corrngations u distance, asshown at 15, and preferably se' run horizontally or the end sill or end plate if the corrugations are positioned vertically) bymeans positioned on both sides of the corrugation and in close proximity thereto. lt may be desirable to use both forms of preventative.

y The corrugations extend to the opposite edfes or' the plate and comprise spaced apart Wa ls 13-14 which converge until they are lin contact (at 15) adjacent the edge of thel plate which provides a Waterproof construction. The Weatherprooing.feature is further assured by Apositioning the j' Walls at their ends in parallel relation for a short curing them'together by rivet 16 or yperhaps Welding them. v

' The Walls 13--14 are connected by tension members 17 'and compression members 18 which are spaced in planes on either side ofthe neutral axis 19-20. The Wider these member'sare, the greater the section modulus of the beam, provided` the tension member/is approximately Vthe same Width Vas the compression member. Thel contour ofv the 'Y corrru-gat-ions may consist of a series of curves instead ot'vstraight lines as illustrated.

' Fig. 7. It will be noted, that the amounty of i corrugation,

the plateshown on either side of the center Yline of the corrugation is the samein Figs.V Y 6,17 and 8. VlVhile the Width (and perhaps the height) of'lthecorrugations may 'Vary` yetl the' length of thev center line of the metal Vof the corrugated portion of the plate nor- Vmaltol .the corrugation is-the same as before the corrugation Was'formedtherein; in other words, the foreshortening of the overall di# mcnsion of the metallicplate, normalv to the is substantially the same throughout the length of the corrugation.
